I recently started gambling on Primedice and I'm suprised that my Martingale system works. I use the Kelly criterion to get my base bet and then I play until I have 1.5 times the amount I had.
My system is pretty simple, I calculate my base bet with 0.001 times the amount I have on hand and then I auto roll away.
My settings are:
Payout: 2.667
Increase on loss: 77%
The formula for the base bet is:
balance * 0.001 * kelly
kelly=(2.667 * 0.3712 - 0.6288) / 2.667 which equals about 13.5% or 0.135
So for example you have 1 Bitcoin your base bet would be 0.000135 Bitcoin.
I recommend a starting balance of 0.01.

Be careful when gambling. There's no guarantee on winning. The odds of losing with this method are about 0.15%
